Whoa! You've been skanked up - it's in the bit under the birthday bit under mine. Maybe you've got to do a certain amount of posts before it comes in or something.
Go post in the echo lounge about it, because I think the powers that be that added the customisation to this board might let you know what's going on.
See if you find somebody with less posts than you that have changed theirs. I'm using Fox to view this place, so unless you've got an extension that somehow blocks things it won't be that. I'm still using Webwasher to block adverts and sometimes scream the house down because I've added a rule that nukes stuff even on the dev server and I can't work it out for weeks.
